Larginine is a semiessential amino acid involved in numerous areas of human biochemistry including ammonia detoxification hormone secretion and immune modulation. Arginine is also well known as a precursor to nitric oxide.Lornithine is a metabolite of arginine in the body formed as a byproduct of the action of the arginase enzyme on arginine. Larginine is required for the body to synthesize nitric oxide which enables the arterial system to retain its youthful elasticity.
Nitric oxide also helps to produce an endothelialderived relaxing factor which is needed by the arterial system to expand and contract with each heartbeat.
